Abstract

The emergence of new operating systems and applications for mobile phones and tablets has necessitated the need for power optimization. Storage space has become another matter of concern as new operating systems have started supporting video codec and formats originally meant for desktop application without compression and conversion. The work presented here tries to identify the region of interest for video by combining the ap-proach of feature extraction with natural statistics for dynamic analysis of the scene. The portion outside the region of interest in the original video is depreciated in order to increase redundancy for pixel value in a frame. With the increase in redundancy the file size gets reduced during encoding. While playing these videos quality and power consumption is tested. Because of saliency model, the change in quality is not notifiable. The result shows that the reduction in power consumption and size of the file varies for different video codecs in different samples. On an average, the power consumption and the file size of video are reduced up to 7.6% and 46% re-spectively. Since usability is a very subjective issue which can vary for different video samples also, the range of variation in power consumption and size is high.
